Agreed. If you would like to keep the home for the long term investment, a modification would be a great avenue to ease the current mortgage payment. If you are not concerned with holding on to this investment any longer, a short sale would be a suitable route to get out of the property without just "walking away".
If you would like to discuss the possibility of opening up these options, feel free to contact me and I'd be happy to help you with some direction. To give you some insight for now, here is our website to give you a little perspective of how a loan modification could help you.

MBSDaily:You need to maximize and i mean MAXIMIZE your attempt at a modification or short sale. Those are two of the best answers in lieu of walking away.
